The present invention provides a coating material that can improve gravure printing characteristics of the printing surface of a printing substrate to favorably transfer an ink fed in the cell of a gravure printing roll to the printing surface of the printing substrate, thereby achieving the beautiful gravure printing. The coating material of the present invention is a coating material for forming a surface layer, serving as a printing surface, on a printing substrate on which gravure printing is to be performed, and the coating material is characterized by including a vinyl chloride-vinyl acetate-unsaturated fatty acid copolymer that includes 80 to 90% by mass of a component of vinyl chloride, 9.2 to 19.5% by mass of a component of vinyl acetate, and 0.1 to 0.8% by mass of a component of an unsaturated fatty acid.

The present invention provides a coating material that can improve gravure printing characteristics of the printing surface of a printing substrate to favorably transfer an ink fed in the cell of a gravure printing roll to the printing surface of the printing substrate, thereby achieving the beautiful gravure printing. The coating material of the present invention is a coating material for forming a surface layer serving as a printing surface on a printing substrate to which gravure printing is to be applied, and the coating material is characterized by including a pigment including an inorganic particulate and a skin layer that is formed on a surface of the inorganic particulate and includes an organic compound.

A gravure printing roll that enables printing of fine dots with a size close to that of cells and enables printing on a print subject, such as a printing substrate, without changing the appearance of the print subject. The gravure printing roll includes: a gravure printing roll body; and cells formed in a peripheral surface of the gravure printing roll body. Each of the cells has an opening with a ratio between a dimension in a circumferential direction of the gravure printing roll body and a dimension in an axial center direction of the gravure printing roll body (dimension in the circumferential direction/dimension in the axial center direction) being 1.15 to 7, and have an opening area of 3900 &#x3bc;mor smaller.

To provide a photocurable fluorinated polymer composition which has a high curing rate, shows little shrinkage before and after photocuring and requires no post treatment such as heat treatment after photocuring and whereby it is possible to obtain a cured resin excellent in heat resistance and weather resistance. According to the photocurable fluorinated polymer composition comprising a fluorinated polymer (A) containing polymerized units derived from a fluoroolefin and polymerized units derived from an unsaturated monomer having an oxetanyl group or a substituted oxetanyl group, and a photoreaction initiator (B), of the present invention, it is possible to provide a photocurable fluorinated polymer composition which has a high curing rate, shows little shrinkage before and after photocuring and requires no post treatment such as heat treatment after photocuring and whereby it is possible to obtain a cured resin excellent in heat resistance and weather resistance.

The present invention has an object to provide a process for producing a hydrolyzable silyl group-containing fluoropolymer which is excellent in storage stability and has a sufficient pot life. At the time of producing a hydrolyzable silyl group-containing fluoropolymer by reacting an isocyanate group of an isocyanate group-containing alkoxysilane to a hydroxy group of a hydroxy group-containing fluoropolymer, the reaction is carried out in the presence a compound containing a specific metal atom at a certain concentration.

A device for coupling pipelines for running cryogenic liquid has: a pair of flanges which are pierced by coupling units respectively and which support the coupling units with the coupling units freely approaching and separating from each other and which form compartments around the coupling units; a pair of inner cover units which open and shut the insides of the coupling units; a pair of outer cover units which open and shut the insides of the compartments of the flanges; and purge lines for purging the insides of the compartments. The process of coupling pipelines by this device has the steps of: opening the outer cover units with the insides of the coupling units shut by the inner cover units; coupling the flanges to each other; purging the inside of a compartment which is formed in the flanges; opening the inner cover units; and coupling the coupling units to each other with the coupling units isolated from the outside air. It can be possible to promptly perform the separation and the coupling of the pipelines with high purity kept. Moreover, the reduction of the cost of the separation and the coupling can be accomplished because the quantity of flushing fluid can be reduced greatly.
